that evap is not all that "frozen up" but the board indicates the heater is not comming on during defrost by the 0 minute duration

you need to test the defrost therm while it is cold and see if it is closed, i suspect you will find it open in which case the board will think defrost is done cause of the open therm and restart the compressor

while all is cold and frosted, initiate defrost and make sure it flashes the "D" if it does unplug fridge, disconnect the white/red connector between the element and therm(one meter probe goes in the white connector) then unplug the large connector on the back wall(other meter probe goes in the terminal for the light blue wire from the therm)

Also, the evap is twice as frozen as last night. I have a pic if you want. The temp was actually starting to go up in freezer and fridge just before I started this. Should I force a manual defrost now or is there anything else you need me to do while it is frosted?
